Really good information, Mike!
This could really be another tip on the RoHS iceberg. I believe that high
lead-content solders have been around for quite a few years, but this could be
that there is a "new" succeptibility for high lead solders associated with the
higher processing temperatures associated with SAC305 assembly processes?
This looks like something that should be hitting the CPUs, as well. The really
sad thing about this is that the general public is oblivious to the uncertain
product quality that they are laying down their money for. And if anyone in
industry tries to wake them, that person's employer will get a blackeye, the we
all know what that will result in for the employee.
Very troubling,
Ed

Niki, Bert and Ed,
Take a look at this article posted on TomsHardware regarding
Nvidia GPU failures. The failures may have been caused by
the use of High Lead solder.

Hi, Bert!
Yes, it seems inconsistent with the stated objectives of RoHS, but it is
a good example of what pushing back with data can achieve.
These high lead-content solders all have very high melting points. They
are used by device manufacturers to make internal interconnects in
devices that have very high power densities.
Best regards,
Ed

Subject: [tinwhiskers] Exemption on high temperature lead solder
Hi,
I have been looking over some of the official RoHS documents and have
seen
that there is an exemption on high temperature lead solder (more than
85%
lead). Not having done any more research on the subject I was
wondering:
* Why the exemption exists?
* Why not use more than 85% lead to circumvent the pure tin problem?
Maybe
the temperature is unacceptably high?
I also noticed that mercury is limited but not banned in fluorescent
lights.
Just thinking of the millions of fluorescent lights being dumped in
landfills
each year I cannot see how this can be viewed as acceptable while ALL
lead
had to be removed from electronics. Furthermore, lead in batteries are
exempt. There is probably more lead in my car battery than in a
thousand PC
motherboards and how many of these batteries end up in landfills each
year?
Just seems strangely warped...
Regards,
Niki
